ABSTRACT
Malignancies are rare in the early neonatal period. Common congenital tumours include malignant teratoma and neuroblastomas. Tumour lysis syndrome is a serious condition usually seen after commencement of chemotherapy for a malignancy. Rare case reports of spontaneous tumour lysis have been reported though not in the newborn period. We report here an instance of tumour lysis syndrome in a newborn with congenital rhabdoid tumour, where the cause was either spontaneous or related to antenatal steroid exposure.

OBJECTIVES: To identify the perinatal risk factors for early-onset Group B Streptococcus (EOGBS) sepsis in neonates after inception of a risk-based maternal intrapartum antibiotic prophylaxis strategy in 2004. DESIGN: Case control study. METHODS: All newborn with early onset GBS sepsis (born between 2004 and 2013) were deemed to be "cases" and controls were selected in a 1:4 ratio. RESULTS: More than three per vaginal (PV) examinations [odds ratio (OR) 8.57, 95% confidence interval (CI) 3.10-23.6] was a significant risk factors. Peripartum fever (OR 3.54, 95% CI 1.3-9.67), urinary tract infection (OR 2.88, 95% CI 1.08-7.63), meconium-stained amniotic fluid (MSAF) (OR 2.52, 95% CI 1.18-5.37) and caesarean section (OR 1.99, 95% CI 1.16-3.43) were also found to be associated with EOGBS sepsis. CONCLUSION: Multiple vaginal examinations are the strongest risk factors for peripartum Group B Streptococcal (GBS) sepsis. The association of MSAF and caesarean section indicates that foetal distress is an early symptom of perinatal GBS infection.
